Recombinant Mouse Antibody (RoAb13) is capable of binding to The extracellular domain of CCR5. This antibody could block HIV infection, also blocks migration of monocytes in response to CCR5 binding chemokines and to inflammatory macrophage conditioned medium.
Figure 1 The antibodies recognize a linear epitope in the N-terminal domain of CCR5.
Dilutions of the four monoclonal antibodies shown were tested for binding to hCCR51–31 coding for the N-terminal extracellular domain of CCR5 by ELISA. The left panel shows binding (as measured by OD at 405 nm) to plates coated with the N-terminal peptide coupled to avidin, while the right panel shows binding to avidin alone.

Figure 2 R&D1801 and RoAb13 recognise overlapping core epitopes in the CCR5 N-terminal domain.
A, R&D1801 or RoAb13 were incubated overnight with competing peptides 1–24 (1 μg/ml) in wells coated with hCCR5₁₋ ₃₁, and binding (shown as OD 405 nm) of antibody was then measured using a rabbit anti-mouse second layer. C—PBS used in place of competitive peptide. B, The peptide sequence of the 24 peptides tested in a. The blue bars shows all peptides which inhibited the binding by more than 50%. C, Diagrammatic representation of the core binding epitope recognized by the two antibodies, defined by peptides which inhibited binding to the whole N-terminal peptide by more than 50%.

Figure 3 Binding of immune sera and RoAb13 to sulphated N-term CCR5.
Dilutions of sera from immunized mice 1–5 or purified RoAb13 supernatant were tested by ELISA for binding to hCCR5₁₋ ₃₁, or an analogue of the same peptide modified by sulfation of tyrosines at position 10 and 14.

C, Flow cytometry showing binding of R&D1801 or RoAb13 or control to PBMC from rhesus macaques (indirect immunofluorescence, using Goat anti-mouse PE conjugate as second layer). The first panel shows binding of a commercially available PE-conjugated anti-rhesus CCR5 antibody (positive control).

Figure 5 RoAb13 inhibits monocyte chemotaxis.
PBMC were incubated in the upper chamber of transwells, while the lower chamber contained medium alone, supernatant of unactivated macrophages, or supernatant of macrophages activated with LPS. RoAb13 Fab fragment or a control Fab fragement were added to some wells as shown. Migrating cells were collected from the lower chamber after three hours. Migration is shown as the proportion of cells in the PBMC premigration sample which migrate to the lower chamber during the assay.

Figure 6 CCR5 MAb dose-response curves of MAb3952-resistant and wild-type Bal (A) and CC1/85 (B) HIV-1 strains in a PBMC-based assay.
A total of 100,000 PBMC were infected with 800 pg p24 of the indicated virus strain in the presence of diluted CCR5 MAb MAb3952 (red), RoAb13 (blue), or 2D7 (black). After incubation for 6 days, virus production was determined using a p24 ELISA. NDC viruses are indicated by filled symbols and continuous lines, and MAb3952-resistant (MAb3952res) virus strains are indicated by open symbols and broken lines.
